Attacks on this boat and other events

24 Aug 1942At 21.55 hrs, HNoMS Potentilla sighted two U-boats on the surface near convoy ONS 122 and began to chase them northwards. They were U-174 and U-755, and the latter was fired on from the 4in gun at a range of about 12 miles, but the shots fell short. Both U-boats managed to escape under cover of darkness within two hours, proceeding at full speed while surfaced. (Sources: ADM reports, KTB U-755)

24 Sep 1942This was a difficult day for U-755. At 05.49 hrs she was fired on by a convoy escort; two hours later she missed convoy SC 100 with a spread four torpedoes. She was attacked from the air at 16.15, and again by an escort at 17.00, and that time damaged so heavily she was forced to return to base.

21 May 1943The British submarine HMS Sickle fired five torpedoes at U-755, but they all missed.

26 May 194306.26 hrs, 13 miles north of Alboran Island in the Mediterranean: the boat was attacked by a British Hudson bomber (500 Sqdn RAF, pilot S/L H.G. Holmes, DFC). Three depth charges were dropped by the aircraft during the first attack run, despite being hit in the port engine by flak, and followed up with two dive-bombing attacks, dropping first two and then one A/S bomb, one of which exploded only five yards (4.6m) off the port beam. The engine damage then forced the aircraft to return to base. One of U-755s crew was killed and two wounded by strafing, and the boat was forced to return to base due to heavy damage. She was sunk in another air attack two days later. (Sources: Franks/Zimmerman)
